In March 1967, a strike broke out at the Rhodiaceta textile factory in the city of Besançon, France. The strike was unusual because the workers refused to dissociate the labor dispute from a social and cultural agenda. Their demands did not refer only to wages and job security, but also to the lifestyle that society imposes on the working class. This documentary is the most direct antecedent of the productions of the French film collectives that will expand in the heat of the events of May 1968.

In early-August 1968, Czech New Wave filmmaker Jan Nemec began filming a documentary about the Prague Spring, a celebration of the newfound liberalization of Czechoslovakia, but the film's subject took a dramatic turn when Soviet tanks rolled through the streets of Prague. Nemec’s footage represented the first proof that the armies of the nations of the Warsaw Pact that crushed the pacific revolution, had not been "invited" into Czechoslovakia, and was used in international news reports, defeating the propagandistic version of the same events fabricated by pro-invasion Communists.

This short film is part of the documentary materials through which the National Strike Council (CNH), the heart of the 1968 student-popular movement in Mexico, disseminated its activities and proposals in university film clubs. As the events surrounding the student struggle continued, this piece and '2 de octubre, aquí México' (1968, also by Menéndez), were modified in terms of content and duration by the filmmaker.
